The greater ani is a large, social cuckoo often seen in small groups along rivers, wetlands, and mangroves. Groups commonly share a single nest and practice cooperative breeding, with multiple adults incubating and feeding the young. Its pale eye and deep, high-arched bill distinguish it from other anis. It often forages near cattle or boats, snatching insects flushed from vegetation.
